Embodiment 1

[0047] Such as figure 1 The shown measuring scale of a self-erecting level includes a base 4, a leveling staff 2 mounted on the base 4 and used in conjunction with the leveling instrument 1, and a leveling staff fixed on the leveling staff 2 and measuring the verticality of the leveling staff 2. A level 7, the level 7 is located on the central axis of the leveling staff 2 and is arranged vertically to the leveling staff 2 . The leveling rod 2 is located above the base 4 and its bottom is installed on the base 4 through a ball joint. The bottom of the leveling rod 2 is provided with a ball joint head 8, and the ball joint head 8 is located at the inner middle part of the base 4. The base 4 is a ball joint base for the installation of the ball joint head 8, and the upper part of the ball joint base is provided with a spherical groove 3 for the ball joint head 8 to snap into. Lock and fix.

[0048] In this embodiment, the level 7 is arranged on the body of the leveling staff 2 ...

Embodiment 2

[0091] In this embodiment, the structure and connection relationship of the measuring scale of the automatic leveling instrument used are the same as those in Embodiment 1.

[0092] In this embodiment, the method for leveling using the measuring scale adopted is different from Embodiment 1 in that: the bottom surface of the base 4 in step one is a circular plane and the radius of the bottom surface is r; step three When carrying out leveling measurement in the center, first measure according to the conventional leveling method, and use the leveling instrument 1 to read the readings of the leveling staff 2 in the two measuring scales respectively, wherein the leveling in the measuring scale installed on the known elevation point A is The reading on scale 2 is denoted as H A , the reading of the leveling staff 2 in the measuring scale installed on the point B to be measured is denoted as H B ; After that, according to the formula H AB =H A '-H B '(3), calculate the elevation...

Abstract

The invention discloses a measuring scale and a measuring method for an automatically-centralized level gauge. The measuring scale comprises a base, a levelling scale arranged on the base and a level for measuring the verticality of the levelling scale, wherein the levelling scale is located above the base, and the bottom of the levelling scale is arranged on the base through a spherical hinge; a spherical hinge head is arranged at the bottom of the levelling scale and is located in the middle of the inner side of the base; the upper part of the base is provided with a spherical groove in which the spherical hinge head is clamped; the spherical hinge head and the base are locked and fixed by a locking piece. The measuring method comprises the following steps: 1, mounting the measuring scale, to be specific, respectively mounting a measuring scale on a known elevation point A and a point B to be measured according to the following processes: placing the measuring scales, adjusting the verticality of the levelling scale and locking and fixing the levelling scale; 2, mounting the level, to be specific, erecting the level between the two measuring scales; 3, carrying out level measurement. The measuring scale and the measuring method disclosed by the invention are reasonable in design, simple and convenient to operate, good in use effect and capable of effectively improving the efficiency and the precision of the level measurement.

Description

technical field [0001] The invention belongs to the technical field of civil engineering measurement, and in particular relates to a measuring scale and a measuring method for an automatic leveling instrument. Background technique [0002] With the continuous development of the national economy and the continuous enhancement of comprehensive national strength, it has driven the comprehensive and rapid development of my country's civil engineering field. In order to achieve the given shape and size of the building being built, the frequency of level gauges is also increasing day by day. During the use of the level, it is inevitable to use the level to measure the ruler. The use of the level measuring scale is mainly used for the measurement of the elevation reference point of the construction engineering survey control network and the measurement of the settlement observation of the factory building and large-scale equipment foundation, so as to control the built structure t...
